Abstract

The subject technology receives at least one signal from a computing device, the at least one signal comprising at least one of a current time, battery power, sensor information, or location information. The subject technology generates a digital sticker, the digital sticker including graphical content indicating information based at least in part based on the at least one signal and media content including an image of a target face, the image of the target face being modified based on at least one of sets of source pose parameters to mimic at least one of positions of a head of a source actor and at least one of facial expressions of the source actor. The subject technology provides augmented reality content for display on a computing device, the augmented reality content including the digital sticker as an overlay on at least a portion of the augmented reality content.
